Referring to fig. 1 to 4, the present embodiment provides an induction cooker, including a bottom case 100 and a panel disposed on the bottom case 100, where the bottom case 100 and the panel jointly enclose an accommodating cavity, and a heat dissipation fan 200, a coil panel 700, and a circuit board assembly 800 are disposed in the accommodating cavity. In practical application, the circuit board assembly 800 includes a display panel 810 and a power board 820, wherein the display panel 810 is a lamp panel, which provides a light source for the functional display area of the induction cooker, and the display lamp on the display panel 810 is controlled to emit light, so as to indicate the working state for the user through the functional display area. The power board 820 controls the operation of the heat dissipation fan 200, the coil panel 700, and the like.

Referring to fig. 1, in the present embodiment, a bottom case 100 of an induction cooker includes a first sidewall 110, a second sidewall 120, a third sidewall 130, and a fourth sidewall 140 sequentially connected along a circumferential direction. Wherein the first sidewall 110 and the third sidewall 130 are oppositely disposed, and the second sidewall 120 and the fourth sidewall 140 are oppositely disposed. A wind shielding rib 600 is arranged in the bottom case 100, a first end of the wind shielding rib 600 is connected with the fourth side wall 140, a second end of the wind shielding rib 600 is connected with the third side wall 120, the accommodating cavity is divided into a first area 150 and a second area 160 by the wind shielding rib 600, the display panel 810 is located in the first area 150, and the heat dissipation fan 200, the coil panel 700 and the power panel 820 are located in the second area 160.

Referring to fig. 2, the wind shielding rib 600 of the present embodiment has an air inlet communicating the first area 150 and the second area 160, an air inlet 300 is disposed in the first area 150 for communicating the first area 150 with the outside so that the outside air enters the first area 150 through the air inlet 300, and an air outlet 500 is disposed in the second area 160 for blowing the air in the second area 150 out of the induction cooker.

In a specific arrangement, at least a portion of the air inlet 300 is located below the display panel 810, so that the space of the display panel installation area is reasonably utilized while ensuring that external cold air can enter the first area 150. At least a portion of the air inlet 300 is communicated with the display panel 810, so that cold air entering the first area 150 through the air inlet 300 can dissipate heat of the display panel 810, and normal operation of the display panel 810 is guaranteed.

Referring to fig. 1 to 4, in the electromagnetic oven of the present embodiment, the heat dissipation fan 200, the coil panel 700, and the power board 820 are arranged in a triangle, the coil panel 700 is located between the heat dissipation fan 200 and the third sidewall 130, and the power board 820 is located between the heat dissipation fan 200 and the fourth sidewall 140. An air outlet 500 is formed on a portion of the third sidewall 130 located in the second region 160 and/or the fourth sidewall 140, and the air outlet 500 is disposed away from the first and second air inlets 310 and 320. The arrangement is such that a part of the wind blown out through the heat dissipation fan 200 is blown toward the coil panel 700, a part is blown toward the power supply board 820, and then the hot wind is directly blown out from the outlet 500 at the rear portion of the bottom chassis 100.

In some examples, the portion of the third sidewall 130 located in the second region 160 and the fourth sidewall 140 are both provided with an air outlet 500, a part of the air blown by the heat dissipation fan 200 blows towards the coil panel 700, and after the coil panel 700 is cooled, the air is directly discharged through the air outlet 500 on the third sidewall 130; another part of the air blown out by the cooling fan 200 is blown toward the power board 820, passes through the heat sink located at the front end of the power board 820, and then passes through the remaining power boards 820 to cool the power board 820, and is directly discharged through the air outlet 500 on the fourth side wall 140.

Because the air outlets 500 are all arranged at the rear positions, the situation that air blown out from the heat dissipation fan 200 is directly discharged from the air outlets 500 without effectively dissipating heat of the coil panel 700 and the power supply board 820 is effectively avoided, so that waste of cooling air is prevented, and effective cooling of the coil panel 700 and the power supply board 820 is guaranteed.

In practical applications, the flowing area of the wind blown by the heat dissipation fan 200 is referred to as a heat dissipation chamber, and the coil panel 700 and the power supply board 820 are located in the heat dissipation chamber. In this embodiment, the wind shielding rib 600 is disposed in the bottom case 100, one end of the wind shielding rib is connected to the fourth sidewall 140, and the other end of the wind shielding rib is connected to the third sidewall 130, and the heat dissipation fan 200, the coil panel 700 and the power board 820 are disposed in the second area 160 surrounded by the wind shielding rib 600, a part of the fourth sidewall 140 and a part of the third sidewall 130, so that the spatial size of the heat dissipation chamber is reduced, and thus the wind blown by the heat dissipation fan 200 can flow through the heating elements such as the coil panel 700 and the power board 820 to a greater extent under the blocking of the wind shielding rib 600, and the wind flowing through the remaining areas without the heating elements is reduced, thereby improving the heat dissipation efficiency of the heating elements such as the coil panel.

Meanwhile, because the first end of the wind-shielding rib 600 is connected with the fourth sidewall 140, the second end is connected with the third sidewall 130, and the coil panel 700 is located in the second area 160 surrounded by the wind-shielding rib 600, a part of the third sidewall 130 and a part of the fourth sidewall 140, a part of the wind-shielding rib 600 is shielded between the coil panel 700 and the second sidewall 120, the wind-out resistance of the coil panel 700 towards one side of the second sidewall 120 is increased, and the wind pressure of the area formed between the coil panel 700 and the fourth sidewall 140 is increased, so that the wind blown out by the heat dissipation fan 200 is blown to the coil panel 700 and the power board 820 to a greater extent under the effect of the wind pressure, and flows out smoothly from the wind outlet 500, thereby not only increasing the airflow flowing to the coil panel 700 and the power board 820, but also avoiding the problem that the heat dissipation efficiency is affected due to the retention of the hot wind in the heat dissipation cavity.

In addition, in this embodiment, the second area 160 where the coil panel 700, the heat dissipation fan 200, the power board 820 and the air outlet 500 are disposed is separated from the first area 150 where the air inlet 300 is disposed by using the wind shielding rib 600, so as to effectively isolate the air inlet area from the heat dissipation area, which can increase the number and the space of the air inlet 300, that is, the air inlet 300 is disposed at each position of the bottom case 100 located in the first area 150, and the condition that the air blown out by the heat dissipation fan 200 blows out from the outside through the air inlet 300 without dissipating the heat of the coil panel 700 and the power board 820 is not yet occurred, so that the amount of cold air entering the second area 160 is increased, and the coil panel 700 and the power board 820 are effectively dissipated.

The arrangement of the wind blocking rib 600 also avoids the situation that when the second sidewall 120 is provided with the air inlet 300 or the air outlet 500, the normal operation of the components of the induction cooker and the user experience are affected due to the fact that insects such as cockroaches enter the coil panel 700 and the power panel 820.

The display panel 810 is separated from other components such as the coil panel 700 by the wind shielding ribs 600, so that the display panel 810 is not affected by the other components, particularly the coil panel 700 and the power supply board 820 which generate a large amount of heat, and the service life of the display panel 810 is prolonged.

In this embodiment, when the wind-shielding rib 600 is specifically disposed, the second end of the wind-shielding rib 600 may extend to a position between the projection of the side of the coil panel 700 facing the second sidewall 120 on the third sidewall 130 and the second sidewall 120, as shown in fig. 1 to 4, that is, the projection of the coil panel 700 on the third sidewall 130 is completely located between the second end of the wind-shielding rib 600 and the fourth sidewall 140, so that the extending length of the wind-shielding rib 600 is reduced while the isolation effect of the wind-shielding rib 600 on the empty region between the coil panel 700 and the second sidewall 120 is ensured, the usage amount of the wind-shielding rib 600 is saved, and the wind-shielding rib 600 is more stable in the bottom case 100.

Referring to fig. 1 to 4, in the present embodiment, the air inlet 300 communicating with the outside may be disposed at one or more positions among the portions of the first side wall 110, the second side wall 120, and the third side wall 130 located in the first area 150. In some examples, the intake vent 300 may also be disposed on the inner bottom wall of the bottom case 100 located in the first area 150, for example, the intake vent 300 may be disposed on the inner bottom wall near the first sidewall 110, or on the inner bottom wall near the second sidewall 120, or on the inner bottom wall near the portion of the third sidewall 130 located in the first area 150, as shown in fig. 1.

Based on the above, the air inlet 300 of this embodiment may be configured such that the bottom case 100 is located on any sidewall and/or inner bottom wall of the first region 150, so that not only the air inlet 300 may be located on the first region 150 and the component may be disposed at a position communicated with the air inlet 300, so as to dissipate heat of the component, but also the position of the air inlet 300 is more flexible, so as to improve the manufacturing efficiency of the induction cooker.

In addition, air inlets 300 may be disposed on any sidewall and bottom wall of the bottom case 100 located in the first area 150 to increase the amount of air entering the first area 150, so as to increase the amount of air flowing through the coil panel 700 and the power board 820, thereby improving the heat dissipation efficiency of the induction cooker.

With continued reference to fig. 1 to 3, the intake vent 300 of the present embodiment may specifically include a first intake vent 310 and a second intake vent 320. Wherein, at least part of the first air inlet 310 is disposed on the first sidewall 110 and/or the bottom wall adjacent to the first sidewall 110, the first air inlet 310 is disposed below the display panel 810, the second sidewall 120 includes a first section 121 adjacent to the first sidewall 110 and a second section 122 away from the first sidewall 110, the first section 121 is connected to the second section 122, and at least part of the second air inlet 320 is disposed on the second section 122 of the second sidewall 120 and/or the bottom wall adjacent to the second section 122.

When the first air inlet 310 of this embodiment is specifically arranged, it may be only arranged on the first side wall 110, so as to avoid the situation that the accumulated water on the tabletop is sucked into the bottom case 100 when the induction cooker works, prolong the service life of the electronic devices in the induction cooker, and avoid the occurrence of unsafe accidents. Of course, the first intake vent 310 may be disposed on the bottom wall near the first sidewall 100. Wherein, the first air inlet 310 may be disposed below the display panel 810. When the display panel 810 is communicated with a portion of the first air inlet 310, the cold air entering the first area 150 through the first air inlet 310 can dissipate heat of the display panel 810.

In some examples, the first air inlet 310 may be further disposed on the first section 121 of the second sidewall 120 close to the first sidewall 110 to increase the amount of cool air entering the first area 150 of the accommodating cavity, so as to increase the amount of cool air entering the second area 160, and improve the heat dissipation efficiency of the coil panel 700 and the power supply board 800.

Similarly, when the second air inlet 320 is specifically arranged, it may be only arranged at the second section 122 of the second side wall 120, so as to avoid the situation that the accumulated water on the table top is sucked into the bottom case 100 when the induction cooker works, prolong the service life of the electronic devices in the induction cooker, and avoid the occurrence of unsafe accidents. Certainly, the second air inlet 320 may also be disposed on the bottom wall of the second section 122 close to the second side wall 120, so as to increase the amount of cold air entering the first area of the accommodating cavity, thereby increasing the amount of cold air entering the second area, and improving the heat dissipation efficiency of the coil panel 700 and the power board 800.

Wherein, this first lateral wall 110 can be towards user's preceding lateral wall, like this, sets up and is provided with first air intake 310 on first lateral wall 110 towards the user, and the user can observe first air intake 310 at any time to when first air intake 310 takes place to block up, the user can in time clear up, with the normal heat dissipation of assurance electromagnetism stove.

The air inlet of the present embodiment includes a first air inlet 650 and a second air inlet 660, a first air storage area 151 is formed between the first air inlet 650 and the first air inlet 310, the first section 121 of the second sidewall 120 is located in the first air storage area 151, and a second air storage area 152 is formed between the second air inlet 660 and the second air inlet 320. A communication channel 153 is further arranged between the first wind storage area 151 and the second wind storage area 152, and the first wind storage area 151 is communicated with the second wind storage area 152 through the communication channel 153.

Referring to fig. 1 and 3, the first air storage zone 151 is specifically an area formed between the first air inlet 650 and the first air inlet 310 of the first sidewall 110 and the first section 121 of the second sidewall 120, and the second air storage zone 152 is specifically an area formed between the second air inlet 600 and the second air inlet 320 of the second sidewall 120. The communication channel 153 is specifically a junction area of the first wind storage area 151 and the second wind storage area 152, as shown by a dashed line frame in fig. 1. It is understood that the communication passage 152 is an area sandwiched between the inner bottom wall and the panel at the boundary of the first and second wind storage areas 151 and 152. In some examples, the communication passage 152 may also be a through hole provided on a baffle at the intersection of the first and second wind storage regions 151 and 152, through which communication between the first and second wind storage regions 151 and 152 is achieved.

The air inlet of the present embodiment may be disposed at a corner of the wind shielding rib 600, and specifically, the first air inlet 650 may be disposed opposite to the first sidewall 110 to reduce a distance between the first air inlet 310 and the first air inlet 650, so that cold air entering the first air storage region 151 through the first air inlet 310 can directly enter the second region 160 through the first air inlet 650. Similarly, the second air inlet 660 may be disposed opposite to the second sidewall 120 to reduce a distance between the second air inlet 320 and the second air outlet 660, so that the cold air entering the second air storage area 152 through the second air inlet 320 can directly enter the second area 160 through the second air inlet 660.

When the induction cooker of this embodiment specifically radiates heat, external cold air enters the first air storage region 151 through the first air inlet 310, wherein a portion of the cold air in the first air storage region 151 enters the second region 160 through the first air inlet 650, and another portion of the cold air enters the second air storage region 152 through the communication channel 153, and then enters the second region 160 through the second air inlet 660. Meanwhile, the outside cold air also enters the second air storage area 152 through the second air inlet 320, wherein a part of the cold air in the second air storage area 152 enters the second area 160 through the second air inlet 660, and the other part of the cold air enters the first air storage area 151 through the communication channel 153, and then enters the second area 160 through the first air inlet 660.

A portion of the cool air in the second region 160 enters the fan cavity 210 of the heat dissipation fan 200, and after being accelerated, the cool air is blown to the coil panel 700 and the power board 820 from the air outlet surface of the fan cavity 210, so as to dissipate heat of the coil panel 700 and the power board 820. Another portion of the cool air in the second area 160 directly flows through the coil panel 700 and the power board 820, and dissipates heat from the coil panel 700 and the power board 820. The fan cavity 210 of the heat dissipation fan 200 is specifically a receiving area formed between the outer shell of the heat dissipation fan 200 and the inner bottom wall of the bottom case 100.

In this embodiment, the first air inlet 310 communicated with the first air storage area 151 is disposed on the first side wall 110, the second air inlet 320 communicated with the second air storage area 152 is disposed on the second section 122 of the second side wall 120, so that the number of the air inlets is increased, the amount of cold air entering the accommodating cavity of the induction cooker is increased, external cooling air enters the accommodating cavity of the induction cooker from the air inlets at different positions, heat is dissipated from heating elements such as the coil panel 700, the power panel 820 and the display panel 810, and the heat dissipation efficiency of the induction cooker is improved.

In practical applications, the first air inlet 310 and the second air inlet 320 may be blocked by external dust or oil. When the air inlet at any one of the first air inlet 310 and the second air inlet 320 is blocked, the external cooling air can enter the first air storage area 151 and the second air storage area 152 through the unblocked air inlet to dissipate heat of the display panel 810, and can enter the second area 160 to dissipate heat of the coil panel 700 and the power panel 820, thereby ensuring normal heat dissipation operation of the induction cooker.

For example, when the first air inlet 310 is blocked, the external cooling air enters the second air storage area 152 through the second air inlet 320 disposed on the second section 122 of the second sidewall 120, a part of the cooling air in the second air storage area 152 enters the second area 160 through the second air inlet 660, and cools the heating elements such as the coil panel 700 and the power board 820, and another part of the cooling air in the second air storage area 152 enters the first air storage area 151 through the communicating channel 153, and then enters the second area 160 through the first air inlet 650, and cools the heating elements such as the coil panel 700, so that the normal heat dissipation of the induction cooker is effectively ensured. It can be seen that when the first air inlet 310 is blocked, the external cold air can enter the first area 150 through the second air inlet 320 to dissipate heat from the display panel 810, and then enter the second area 160 through the air inlet to dissipate heat from the coil panel 700 and the power board 820, thereby ensuring normal cooling of the induction cooker.

Similarly, when the second air inlet 320 is blocked, the external cooling air may enter the first air storage region 151 through the first air inlet 310, a part of the cooling air located in the first air storage region 151 directly enters the second region 160 through the first air inlet 650, and the other part of the cooling air enters the second air storage region 152 through the communicating channel 153, and then enters the second region 160 through the second air inlet 660 to dissipate heat of the coil panel 700 and the power board 820. It can be seen that when the second air inlet 320 is blocked, the external cold air can enter the first region 150 through the first air inlet 310 to dissipate heat of the display panel 810, and then enter the second region 160 through the air inlet to dissipate heat of the coil panel 700 and the power board 820, thereby ensuring normal cooling of the induction cooker.

Based on the above, the first air inlet 310 and the second air inlet 320 are arranged, so that the problem that the normal heat dissipation of the induction cooker is affected due to the fact that the external cold air cannot enter the accommodating cavity due to the blockage of the air inlet arranged on one side wall of the conventional induction cooker is effectively solved.

In addition, in the present embodiment, the first wind storage area 151 and the second wind storage area 152 are communicated through the communication channel 153, and compared with the first wind storage area 151 and the second wind storage area 152 which are isolated from each other, a vortex phenomenon caused by collision between the cooling wind entering the bottom case 100 and wind deflectors is effectively avoided, that is, a dead angle area is generated before the cold wind enters the second area 160, so that the cold wind cannot smoothly enter the second area 160, or even a part of the cooling wind flows back to the first wind inlet 310 or the second wind inlet 320 and is discharged outside, so that a loss of a part of the cooling wind is avoided, a difference between the wind entering the bottom case 100 through the first wind inlet 310 and the second wind inlet 320 and the wind entering the second area 160 is reduced, so that the cooling wind of the first wind storage area 151 and the second wind storage area 152 enters the second area 160 to a greater extent, thereby increasing the cooling wind flowing through the heating elements such as the coil panel 700, thereby improving the heat dissipation efficiency of the induction cooker.

Referring to fig. 2, in the present embodiment, the first air storage area 151 and the second area 160 are communicated through the first air inlet 650, and on the first hand, a path of the cooling air entering the second area 160 of the bottom case 100 from the first air inlet 310 is shortened, so that the cooling air entering the first air storage area 151 from the first air inlet 310 can directly enter the fan cavity 210 of the heat dissipation fan 200 through the first air inlet 650 after passing through the first air storage area 151, and the air consumption of the cooling air in the first air storage area 151 is reduced, thereby ensuring the cooling air volume entering the second area 160, and improving the heat dissipation efficiency of other heating elements, and on the other hand, the cooling air in the second air storage area 152 can also flow to the first air storage area 151 and enter the second area 160 through the first air inlet 650, thereby ensuring the heat dissipation efficiency of other heating elements.

Similarly, the second air storage area 152 is communicated with the second area 160 through the second air inlet 660, so that a path of cooling air entering the second area 160 from the second air inlet 320 is shortened, air consumption of the cooling air entering the second area 160 from the second air storage area 152 is reduced, meanwhile, a part of air flow in the first air storage area 151 can enter the second air storage area 152 through the communicating channel 153 and enter the second area 160 through the second air inlet 660, and therefore the cooling air entering the accommodating cavity through the first air inlet 310 can enter the second area 160, and effective heat dissipation is performed on other heating elements.

In addition, when any one of the first air inlet 650 and the second air inlet 660 is blocked, the cooling air entering the first air storage region 151 and the second air storage region 152 through the first air inlet 310 and the second air inlet 320 can enter the second region 160 through the unblocked air inlet, thereby ensuring effective heat dissipation of other heat generating elements inside the bottom case 100.

The first air inlet 650 and the second air inlet 660 can be arranged in a penetrating manner, in other words, the first air inlet 650 and the second air inlet 660 together form a communicated air inlet, so that cold air in the first air storage area 151 and the second air storage area 152 can more smoothly enter the second area 160 through the air inlet with the larger caliber, thereby reducing air volume loss on a path entering the second area 160, and further improving heat dissipation efficiency of other heating elements.

In some examples, the first air inlet 650 and the second air inlet 660 may be spaced apart from each other, so that when any one of the first air inlet 650 and the second air inlet 660 is blocked, the cooling air entering the first air storage region 151 and the second air storage region 152 through the first air inlet 310 and the second air inlet 320 may enter the second region 160 through the unblocked air inlet, so as to effectively dissipate heat of other heat generating components inside the bottom case 100.

Referring to fig. 1 to 3, in the present embodiment, the heat dissipation fan 200 is disposed close to the air inlet, so that the cooling air entering the second area 160 through the air inlet can enter the fan cavity 210 of the heat dissipation fan 200 to a greater extent, that is, the cooling air entering the heat dissipation fan 200 is increased, so that the high-speed cooling air blowing to the heating elements such as the coil panel 700 and the power board 820 is increased, and further, the heat on the coil panel 700 and the power board 820 is effectively taken away, and the heat dissipation efficiency of the electromagnetic oven is improved.

In a specific implementation, the projection of the heat dissipation fan 200 on the second sidewall 120 is located at the second section 122 of the second sidewall 120, in other words, the fan cavity 210 of the heat dissipation fan 200 is arranged opposite to the second section 122 of the second sidewall 120, so that the cooling air entering the second air storage area 152 through the second air inlet 320 can directly enter the fan cavity 210 of the heat dissipation fan 200, compared with the case that the heat dissipation fan 200 is arranged at a position close to the first sidewall 110, on one hand, the spatial size of the first air storage area 151 is increased, thereby facilitating the arrangement of a heating element in the first air storage area 151, and the cooling air in the first air storage area 151 dissipates heat to the heating element; on the other hand, the sizes of the part of the first air storage area 151 and the communication channel 153 of the first section 121 of the second side wall 120 are also increased, so that the cold air of the part of the first air storage area 151 near the first section 121 of the second side wall 120 can smoothly enter the second air storage area 152 and the fan cavity 210 of the heat dissipation fan 200 through the communication channel 153, that is, the loss of the cooling air near the connection between the first side wall 110 and the second side wall 120 is reduced, and the cooling air volume entering the fan cavity 210 of the heat dissipation fan 200 is increased.

In practical application, the heat dissipation fan 200 includes a fan blade, a fan bracket and a housing surrounding the fan blade. The fan blades are fixed on a rotating shaft in the center of the fan support, and two ends of the fan support are fixed on the shell. In this embodiment, a vent (not shown in the figure) is disposed on the housing of the heat dissipation fan 200, and the vent is communicated with the air inlet, so that cold air entering the second region 160 through the air inlet can directly enter the fan cavity 210 of the heat dissipation fan 200 through the vent, on one hand, the cooling air volume entering the fan cavity 210 of the heat dissipation fan 200 is ensured, and on the other hand, the housing of the heat dissipation fan 200 further plays a role in blocking the cooling air in the heat dissipation fan 200 from entering the first air storage region 151 or the second air storage region 152, so as to improve the cooling air volume blown out from the air outlet surface of the heat dissipation fan 200.

It is understood that the ventilation opening may be an opening opened on the outer case, and of course, in some examples, the ventilation opening may also be a gap formed between the bottom end of the outer case and the inner bottom wall of the bottom case 100. The present embodiment does not limit the specific arrangement of the vents.

The cooling fan 200 of the present embodiment is specifically an axial flow fan. The air inlet surface of the axial flow fan is positioned on the bottom surface of the heat radiating fan 200, the air outlet surface is positioned on the top surface of the heat radiating fan 200, and the air flow direction is in the vertical direction from bottom to top. During specific work, cooling air entering the bottom of the fan cavity 210 through the first air inlet 220, the second air inlet 230 and the ventilation opening of the heat dissipation fan 200 is concentrated to the top air outlet surface of the heat dissipation fan 200 under the high-speed rotation of the fan blades, and then enters the coil panel 700 and the power board 820 from the top air outlet surface, so that other heating elements such as the coil panel 700 and the like are effectively dissipated. In addition, the axial flow fan is low in cost, so that the manufacturing cost of the induction cooker is reduced.

Because the cooling fan 200 of this embodiment is axial fan, this axial fan's lower surface is the air inlet face, and cooling fan 200's upper surface is the air outlet face. The top of the first air inlet 650 and/or the second air inlet 660 is flush with or lower than the air inlet surface of the heat dissipation fan 200, so that the cooling air in the first air storage region 151 and/or the second air storage region 152 can smoothly enter the air inlet surface of the heat dissipation fan 200, then rotate to the top air outlet surface under the action of the fan blades, and then be discharged to the heat dissipation region. The heat dissipation area 190 is specifically an area where the coil panel 700, the power board 820, and the like are disposed in the second area 160.

In addition, the above arrangement prevents the cooling air in the fan cavity 210 of the heat dissipation fan 200 higher than the air inlet surface from flowing back to the first air storage region 151 and/or the second air storage region 152 from the first air inlet 650 and/or the second air inlet 660, so as to ensure the air outlet amount of the air outlet surface of the heat dissipation fan 200, thereby improving the air amount flowing through other heating elements such as the coil panel 700 and the like, and ensuring the heat dissipation efficiency.

Referring to fig. 1 to 3, when specifically arranged, the wind-blocking rib 600 of the present embodiment includes a first wind-blocking rib 610 and a second wind-blocking rib 620 that surround the periphery of the fan cavity 210 of the heat dissipation fan 200. A first end of the first wind blocking rib 610 is connected with a first end of the second wind blocking rib 620, and a first wind inlet 650 is formed between the first wind blocking rib 610 and the inner bottom wall of the bottom case 100; a second air inlet 660 is formed between the second air blocking rib 620 and the inner bottom wall of the bottom chassis 100.

Taking the first wind blocking rib 610 as an example, a part of the bottom end of the first wind blocking rib 610 in the extending direction may be fixed on the inner bottom wall of the bottom case 100, and a gap is formed between the part of the bottom end and the inner bottom wall of the bottom case 100, and the gap is used as the first wind inlet 650 of the embodiment. Of course, in some examples, a gap is formed between all bottom ends of the first wind blocking rib 610 and the inner bottom wall of the bottom case 100, and the gap is used as the first wind inlet 650 of the present embodiment.

This embodiment sets up first wind blocking muscle 610 between first wind storage area 151 and cooling fan 200's fan chamber 210 to the lateral part towards first wind storage area 151 of cooling fan 200's fan chamber 210 separates, thereby avoids getting into the air current in cooling fan 200's fan chamber 210 and spills from the side, and causes the influence to other heat element's radiating efficiency.

The second wind-blocking rib 620 has a similar structure and technical effect to the first wind-blocking rib 610, and is not described herein again.

In addition, in the embodiment, the first air inlet 650 and the second air inlet 660 are disposed on the wind blocking rib 600, so as to reasonably utilize the components in the bottom case 100, thereby reducing the component arrangement of the induction cooker and improving the assembly efficiency of the induction cooker.

The wind blocking rib 600 of this embodiment can be integrated with the bottom case 100 when specifically being fixed, so not only the structure of the induction cooker is simplified, but also the connection strength between the wind blocking rib 600 and the bottom case 100 is improved, so that the wind blocking rib 600 is more firmly fixed on the bottom case 100, thereby ensuring the blocking effect of the wind blocking rib 600 on the lateral air flow of the heat dissipation fan 200, and simultaneously also ensuring the stability of the first air inlet 650 and the second air inlet 660 formed between the bottom ends of the first wind blocking rib 610 and the second wind blocking rib 620 and the inner bottom wall of the bottom case 100 respectively.

In some examples, the wind shielding rib 600 is also provided separately from the bottom case 100, and the wind shielding rib 600 is fixed to the bottom case 100. For example, when a portion of the wind shielding rib 600 contacts with the inner bottom wall of the bottom case 100, a slot may be disposed on the bottom case 100, and a portion of the wind shielding rib 600 in the length direction may be clamped in the slot of the bottom case 100, so as to fix the wind shielding rib 600 to the bottom case 100, and at the same time, it is ensured that an air inlet is formed between the bottom end of the portion of the wind shielding rib 600 in the length direction and the inner bottom wall of the bottom case 100. Of course, a part of the bottom end of the wind shielding rib 600 may be adhered to the inner bottom wall of the bottom case 100, so that the wind shielding rib 600 is stably fixed to the bottom case 100. In other examples, the windshield rib 600 and the bottom case 100 may be connected in other manners, and the present embodiment does not limit the connection manner between the windshield rib 600 and the bottom case 100.

When there is a gap between all bottom ends of the wind-shielding rib 600 in the extending direction and the inner bottom wall of the bottom chassis 100, the side wall of the wind-shielding rib 600 and the inner wall of the bottom chassis 100 may be connected by a fixing member such as a connecting rod. When the fixing is carried out, the fixing of the wind shielding rib 600 can be realized by connecting the two ends of the connecting rod with the side wall of the wind shielding rib 600 and the inner wall of the bottom case 100 respectively.

In addition, the first wind-blocking rib 610 and the second wind-blocking rib 620 of the wind-blocking rib 600 may also be connected to the heat dissipation fan 200. For example, the first wind blocking rib 610 and the second wind blocking rib 620 may be connected to a bracket of the heat dissipation fan 200. Wherein, this first wind-break muscle 610 and second wind-break muscle 620 can the snap-on cooling fan 200's support, also can guarantee the steadiness of this first wind-break muscle 610 and second wind-break muscle 620 through mounting such as fix with screw on this support, guarantee that this first wind-break muscle 610 and second wind-break muscle 620 effectively stop the air current that cooling fan 200's lateral part spilt.

Referring to fig. 2, the bottom case 100 of the present embodiment further includes a support rib 400; the support rib 400 is located between the wind shielding rib 600 and the inner bottom wall of the bottom chassis 100, and is used to support the wind shielding rib 600, so as to ensure the stability of the wind shielding rib 600 in the vertical direction. Specifically, the support rib 400 is disposed near the first air inlet 650 and/or the second air inlet 660 to ensure stability of the second air inlet 660 formed between the bottom end of the first air inlet 650 and/or the second air inlet 620 formed between the bottom end of the first air blocking rib 610 of the wind blocking rib 600 and the inner bottom wall of the bottom chassis 100.

For example, the support rib 400 may be disposed at a side of the first air inlet 650 far from the second air inlet 660 to further ensure stability of the first air inlet 650 formed between the bottom end of the first wind blocking rib 610 and the inner bottom wall of the bottom chassis 100, thereby ensuring that the air flow in the first air storage region 151 can enter the fan cavity 210 of the heat dissipation fan 200 through the first air inlet 650.

Or, the support rib 400 is disposed at a side of the second air inlet 660 far from the first air inlet 650, so as to further ensure stability of the second air inlet 660 formed between the bottom end of the second air blocking rib 620 and the inner bottom wall of the bottom chassis 100, thereby ensuring that the air flow in the second air storage area 152 can enter the fan cavity 210 of the heat dissipation fan 200 through the second air inlet 660.

In some examples, the support rib 400 is disposed at a connection portion between the first air inlet 650 and the second air inlet 660, as shown in fig. 3, so that the support rib 400 is disposed at one position to realize stability of the first air inlet 650 and the second air inlet 660, that is, on the basis of ensuring stability of the first air inlet 650 and the second air inlet 660, thereby simplifying structural arrangement in the bottom case 100 and improving assembly efficiency of the induction cooker.

In this embodiment, the distance between the bottom ends of the first wind-blocking ribs 610 and/or the second wind-blocking ribs 620 and the inner bottom wall of the bottom case 100 is 3mm to 30mm, and the included angle between the bottom ends of the first wind-blocking ribs 610 and/or the second wind-blocking ribs 620 and the inner bottom wall of the bottom case 100 is-15 ° to 15 °.

The first wind-shielding rib 610 will be specifically described below as an example.

Through setting up the interval between the bottom with first wind-blocking muscle 610 and the interior diapire of drain pan 100 in above-mentioned within range, not only make the air current that is located in first wind district 151 can only get into heat dissipation fan 200's fan chamber 210 through this first income wind gap 650 to a great extent, but also avoided the inside air current of heat dissipation fan 200 to flow backward to first wind district 151 from this first income wind gap 650, thereby further ensured the amount of wind in heat dissipation fan 200, thereby guarantee the amount of wind of other heating elements of flowing through, ensure the radiating efficiency of electromagnetism stove.

Referring to fig. 2, an included angle between the bottom end of the first wind blocking rib 610 and the inner bottom wall of the bottom chassis 100 may be denoted as θ, and in this embodiment, the included angle θ is set between-15 ° and 15 °. It can be understood that, when the included angle θ is greater than 0 °, the bottom end of the first wind blocking rib 610 is inclined upward; when the included angle θ is smaller than 0 °, the bottom end of the first wind-shielding rib 610 is inclined downward. Therefore, the angle of the upward inclination of the bottom end of the first wind-shielding rib 610 of the present embodiment is set to be not more than 15 °, and the angle of the downward inclination of the bottom end of the first wind-shielding rib 610 is set to be not more than 15 °.

Specifically, because the distance between the inner bottom wall of the bottom case 100 and the panel is limited, thereby limiting the maximum thickness of the first wind blocking rib 610, the present embodiment sets the angle of the upward inclination of the bottom end of the first wind blocking rib 610 to be not more than 15 °, effectively avoiding the condition that the angle of the upward inclination of the bottom end of the first wind blocking rib 610 is too large and the thickness of one portion of the first wind blocking rib 610 is too small, thereby ensuring the mechanical strength of the first wind blocking rib 610, and further improving the stability of the first air inlet 650, and simultaneously ensuring the effective blocking of the wind inside the heat dissipation fan 200. In addition, the angle of the downward inclination of the bottom end of the first wind blocking rib 610 is set to be not more than 15 °, the situation that the distance between the bottom end of the first wind blocking rib 610 and the inner bottom wall of the bottom case 100 is too small to cause a part of the first wind blocking rib 610 to block the cooling wind is avoided, namely, the situation that the cooling wind is collided with the first wind blocking rib 610 when entering the fan cavity 210 of the heat dissipation fan 200 through the first wind inlet 650 and the cooling wind is lost is effectively avoided, so that the cooling wind in the first wind storage area 151 can smoothly enter the fan cavity 210 of the heat dissipation fan 200 from the first wind inlet 650.

Wherein, the width of the first wind-blocking rib 610 and/or the second wind-blocking rib 620 in the vertical direction is 3mm to 27 mm; the length of the first wind blocking rib 610 and/or the second wind blocking rib 620 in the horizontal direction is 20mm to 110 mm.

By setting the length and width of the first wind-shielding rib 610 and/or the second wind-shielding rib 620 within the above range, effective isolation of the heat dissipation fan 200 is ensured, the mechanical strength of the wind-shielding rib 600 is ensured, and the wind-shielding rib 600 is prevented from being deformed or even broken due to impact of airflow.

Simultaneously, through keeping off the width setting of first wind muscle 610 and/or second wind muscle 620 on vertical direction in above-mentioned within range, on the basis of guaranteeing the height in the certain extent in the income wind gap that forms between the bottom of this wind muscle and the interior diapire of drain pan 100, the width that has prevented the muscle of keeping off the wind is too big and make the electromagnetism stove in the transportation top and the panel of this wind muscle bump, cause the damage to the muscle of keeping off the wind or even the panel, thereby guaranteed the intact of electromagnetism stove in the transportation.

It is understood that, in a specific arrangement, widths of the first and second wind blocking ribs 610 and 620 in a vertical direction may be adjusted according to a distance between an inner bottom wall of the bottom case 100 and an inner surface of the panel.

Referring to fig. 1 and 3, the wind-shielding rib 600 of the present embodiment further includes a third wind-shielding rib 630 and a fourth wind-shielding rib 640. Wherein, one end of the third wind blocking rib 630 is connected with the second end of the first wind blocking rib 610, and the other end of the third wind blocking rib 630 extends to the fourth sidewall 140. One end of the fourth wind-blocking rib 640 is connected to the second end of the second wind-blocking rib 620, the other end of the fourth wind-blocking rib 640 extends to the third sidewall 130, and a second wind-storage area 152 is formed between the second wind-blocking rib 620, the fourth wind-blocking rib 640, a portion of the third sidewall 130 and the second sidewall 120.

Specifically, the fourth wind-blocking rib 640 is disposed between the coil panel 700 and the second sidewall 120, and the coil panel 700 and the power board 820 are disposed between the fourth wind-blocking rib 640 and the fourth sidewall 140, that is, the spatial dimension of the heat dissipation chamber of the induction cooker is reduced, so that wind energy blown out from the air outlet surface of the heat dissipation fan 200 flows through the main heating elements such as the coil panel 700 and the power board 820 to a greater extent, and the amount of wind flowing through the rest areas where no heating element is disposed is reduced, and the situation that hot wind flowing through the heating elements such as the coil panel 700 and the power board 820 flows into the second wind storage area 152 from the area between the coil panel 700 and the second sidewall 120 is avoided, and finally the hot wind continues to be introduced into the heat dissipation fan 200 occurs, so that the wind entering the heat dissipation fan 200 is cooled wind, and the heat dissipation effect of the heating elements such as the coil panel 700 is ensured.

In addition, the second air storage area 152 is formed among the second air blocking rib 620, the fourth air blocking rib 640, a part of the third side wall 130 and the second side wall 120, so that the number of the second air inlets 320 on the second side wall 120 can be increased, the air inlet amount of the cooling air is increased, and the heat dissipation efficiency of the heating element is improved. For example, the second air inlets 320 may be formed at the second section of the second sidewall 120 along the length direction.

Referring to fig. 1, in addition, in the present embodiment, a second air inlet 320 may be further disposed on a side of the third sidewall 130, which is located on the fourth wind blocking rib 640 and faces the second sidewall 120. Therefore, on one hand, the number of the second air inlets 320 is increased, so that the amount of cold air entering the second air storage area 152 is increased, and further, the amount of cold air flowing through the coil panel 700 and the power panel 820 is increased; on the other hand, if the display panel 810 disposed in the first region 150 is communicated with the second air inlet 320, the heat dissipation efficiency of the display panel 810 can be effectively improved.

In specific implementation, a heating element can be disposed at any position of the second air storage area 152, and the cold air entering the second air storage area 152 through the second air inlet 320 close to the heating element can dissipate heat of the heating element effectively.

The second air inlet 320 is arranged at the portion of the third side wall 130 located in the first area 150, so that the air entering the second air storage area 152 through the second air inlet 320 of the portion flows towards the first side wall 110 directly, and thus the air can smoothly reach the air inlet through the area between the fourth air blocking rib 640 and the second side wall 120, and the air consumption on the flow path of the second air storage area 152 is reduced, meanwhile, when the second air inlet 320 is also arranged on the second section 122 of the second side wall 120, the cold air entering the second air storage area 152 through the second air inlet 320 of the second section 122 can be further blown to the air inlet by the cold air blown from the second air inlet 320 of the third side wall 130, so that the loss of the air of the second air storage area 152 before reaching the air inlet is reduced, and the amount of the cold air entering the second area 160 is ensured.

The third wind-blocking rib 630 of this embodiment is disposed opposite to the first sidewall 110, the third wind-blocking rib 630, the first wind-blocking rib 610, the first segment 121 of the second sidewall 120, the first sidewall 110, and a part of the fourth sidewall 140 jointly enclose the first wind-storage area 151, in other words, the third wind-blocking rib 630 effectively isolates the first wind-storage area 151 from the second area 160, so that the cooling wind entering the first wind-storage area 151 through the first wind inlet 300 only directly enters the fan cavity 210 of the second area 160 through the wind inlet, thereby increasing the cooling wind volume entering the fan cavity 210 of the heat dissipation fan 200.

Referring to fig. 1 to 3, the display panel 810 is specifically disposed in the first air storage region 151 between the third wind shielding rib 630 and the first sidewall 110, so that cold wind entering the first air storage region 151 through the first air inlet 300 can directly dissipate heat of the display panel 810, and then enter the fan cavity 210 of the heat dissipation fan 200 of the second region 160, so as to dissipate heat of other heating elements of the induction cooker, and the temperature of the cold wind does not rise significantly after passing through the display panel 810, thereby effectively dissipating heat of subsequent heating elements.

Referring to fig. 2, in the present embodiment, a partition 161 is disposed between the fan chamber 210 of the heat dissipation fan 200 and the coil panel 700; and/or a partition plate 161 is arranged between the fan cavity 210 of the heat radiation fan 200 and the power panel; a fan outlet is formed between the upper end surface of the partition 161 and the panel of the induction cooker.

Taking the case where the partition 161 is provided between the fan chamber 210 of the heat dissipation fan 200 and the coil panel 700 as an example. Due to the arrangement of the partition board 161, cold air in the heat dissipation fan 200 is fully accelerated and then blown out from the fan air outlet at the top end of the partition board 161, the blowing-out speed of the cold air is increased, the flow resistance entering the coil disc 700 is reduced, and the heat dissipation efficiency is further ensured. The partition 161 can allow the cooling air to flow along a predetermined path, that is, after the cooling air in the heat dissipation fan 200 is blown out through the fan outlet, the cooling air is blocked by the partition 161 to flow to the region on the right side of the coil panel 700, so as to prevent a part of the cooling air from being blown out from the left side gap of the coil panel 700 and affecting the air volume entering the coil panel 700 and the power board 820.

The partition 161 extends between the coil panel 700 and the power board 820, so that the heat radiation between the coil panel 700 and the power board 820 can be reduced to a certain extent, and the mutual influence of the heat of the coil panel 700 and the power board 820 is avoided.

Further, the upper end surface of the partition 161 is flush with or higher than the lowest surface of the fan blade of the heat dissipation fan 200.

It can be understood that the lowest surface of the fan blades of the heat dissipation fan 200 is the air inlet surface of the heat dissipation fan 200. In the present embodiment, the partition 161 is blocked between the air inlet surface of the heat dissipation fan 200 and the inner bottom wall of the bottom chassis 100, so as to prevent the cooling air that has not been accelerated in the heat dissipation fan 200 from being blown out through the gap between the lowest surface of the fan blade of the heat dissipation fan 200 and the inner bottom wall of the bottom chassis 100, thereby ensuring that the cooling air is blown out from the air outlet surface of the heat dissipation fan 200 at a high speed, smoothly flows through the coil panel 700 and the power board 820, and is discharged from the air outlet 500, effectively overcoming the resistance of flowing through the coil panel 700 and the power board 820, and ensuring the heat dissipation effect on the coil panel 700 and the power board 820.

Example two

Fig. 5 is a schematic view of an internal structure of the induction cooker according to the second embodiment; fig. 6 is a top view of fig. 5. Referring to fig. 5 and 6, unlike the first embodiment, the second end of the wind-shielding rib 600 of the present embodiment extends to between the coil disk 700 and the third side wall 130, that is, the projection of the coil disk 700 on the third side wall 130 is located between the second end of the wind-shielding plate 161 and the fourth side wall 140.

Specifically, one end of the fourth wind-blocking rib 640 of the wind-blocking rib 600, which deviates from the second wind-blocking rib 620, extends to a position between the coil panel 700 and the third side wall 130, so that the area between the corner positions of the coil panel 700 and the second side wall 120 and the third side wall 130 is isolated by the partial fourth wind-blocking rib 640 close to the third side wall 130, so that the air outlet at the rear of the left side of the coil panel 700 is effectively blocked by the partial fourth wind-blocking rib 640, that is, the air outlet resistance of the coil panel 700 towards the rear of one side of the second side wall 120 is increased, and the amount of cold air flowing from the heat-radiating fan 200 to the coil panel 700 and the power supply board 820 is increased. In addition, the portion of the wind shielding rib 600 located at the rear of the side of the coil panel 700 guides the hot wind flowing through the coil panel 700, so that the wind at the coil panel 700 smoothly flows to the wind outlet 500 and is timely discharged to the outside from the wind outlet 500, thereby preventing the hot wind in the bottom case 100 from being unable to be timely discharged to the outside to affect the heat dissipation efficiency of the heating elements such as the coil panel 700 and the power board 820.

In a specific implementation, as shown in fig. 5, a portion of the wind-shielding rib 600 of the present embodiment, which is close to the third sidewall 130, may be sequentially disposed around the outer periphery of the coil panel 700 toward the second sidewall 120 and the outer periphery toward the third sidewall 130.

For convenience of description, the present embodiment provides the fourth wind-blocking rib 640 of the wind-blocking rib 600 to include a first portion 641, a second portion 642 and a third portion 643 in the length direction, wherein the first portion 641 of the fourth wind-blocking rib 640 is disposed opposite to the second sidewall 120, and the second portion 642 is enclosed in the partial outer circumference of the coil panel 700 facing the second sidewall 120 and the third sidewall 130, so that the outer edges of the coil panel 700 facing the second sidewall 120 and the third sidewall 130 can be effectively isolated from other vacant areas by the second portion 642 of the wind-blocking rib 600, and thus, the wind blown by the heat dissipation fan 200 is further concentrated on the disposition area of the coil panel 700 and the power supply board 820. One end of the third portion 643 is connected to one end of the second portion 642, and the other end is connected to the third sidewall 130, so that the wind shielding rib 600 effectively separates the first area 150 and the second area 160.

The third portion 643 of the fourth wind-blocking rib 640 may be perpendicular to the third sidewall 130, or may be inclined toward the fourth sidewall 140, so as to further reduce the spatial size of the second area 160, and further increase the cold airflow blown by the heat dissipation fan 200 to the coil panel 700 and the power board 820.

In some examples, the third portion 643 may also be inclined toward the second sidewall 120 to increase the number of the air outlets 500, so that the hot air in the heat dissipation chamber can be rapidly discharged to the outside.

In this embodiment, the wind shielding ribs 600 surrounding the coil panel 700 further block and guide the hot wind blown out from the coil panel 700, so that the hot wind flows to the air outlet 500 along with the extending direction of the wind shielding ribs 600, and is then discharged out of the induction cooker, thereby preventing the hot wind from being retained in the heat dissipation cavity to affect the cooling of the coil panel 700 and the power board 820.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
